About this map

The Horseshoe Hills dominate this portion of the Montana landscape, defining a series of deeply etched drainages that flow toward the northern and southern boundaries. High-elevation features like Ellison Flat provide a stark contrast to the intricate network of gulches, including Roy Gulch, Garden Gulch, and Home Gulch, which suggest a long history of water-driven erosion and seasonal runoff. The boundary between Broadwater and Gallatin counties cuts across the northwest corner near Sixteenmile Creek, a primary waterway in this rugged ranching and timber environment.

Several named water sources such as Dunbar Spring, Townsend Spring, and Williams Spring indicate the importance of reliable water points for livestock and land management in this arid terrain. These features, along with Quarry Gulch and Whiskey Gulch, provide localized landmarks that help researchers and historians trace old land-use patterns and property boundaries in a region defined by its topography rather than urban development.
